What is Cloud Computing?
“A pool of abstracted, highly
scalable, and managed compute
infrastructure capable of hosting
end-customer applications and
billed by consumption”
Internet
Where does the term “Cloud” come from ?
“Cloud” is widely used as a metaphor for the Internet
Internet is the foundation of Cloud computing
Definition
In Simple Terms, Cloud offers…
Pay-per-use for computation power
Virtually infinite computation resources
Automatic on-demand scalability

What is Cloud Computing?
An Analogy - Electricity
“Computation Power” is now available like Electricity
You pay for what you use.
You rely on a trusted third-party providers
Grid computing is a collection of
servers that are clustered together to
attack a single problem. For a period of
time, the entire resources of the grid
are available to an user to tackle a
particularly difficult compute problem.
- Rich Wolski, University of California
Grid Computing Utility Computing
Metered use of computational resources
Origin from utility services (Electricity)
Variants

Why Cloud Computing?
Eliminates capacity planning and sizing
Prevents ‘success disaster’
Eliminates scalability issues and risk of failure
Savings on Capital Investment
Savings on Data Center Space, Power and
Cooling
Minimizes Operational costs
Reduces TCO Reduces Risks
Re-invest saved Capex on new initiatives
Focus on business, not on infrastructure
Save on operations manpower
Better Budget Utilization
Quicker Time to Market
Create dev and test environments on the fly
Rely on speed & stability of the Cloud
provider
Remain Competitive

Public vs. Private Cloud
Cloud Choices
Exclusive environment
Limited on-demand capabilities
Private Cloud
On-demand resources, scalability
Shared environment
Public Cloud
Requires Initial Capital Investment
Cloud setup within Org’s data center
Control on security and audit
Based on basic virtualization
Limited on-demand scaling
On-Premise Private Cloud
Exclusive, but hosted by a third party
Limited on-demand scaling
Expensive than public cloud
Cheaper than on-premise private cloud
Possibility of co-location
Externally Hosted Private Cloud
Hybrid Cloud
Public + Private cloud

Google App Engine – An Overview
• Cloud computing – Only PaaS & SaaS, No IaaS
• Initially started with Python Runtime
• Recently added support for Java
• Can deploy standard J2EE WAR Files
• Requires a special deployment descriptor
• Provides simple storage as integrated feature
• Storage supports GQL – Google Query Language
